Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery aluminum shell processing, and more specifically, to a lithium battery aluminum shell surface processing device. Background Art

[0002] The aluminum shell of a lithium battery is an aluminum alloy shell used to encapsulate lithium batteries. During the production and processing of lithium batteries, in order to reduce the oxidation and rust on the surface of the aluminum shell of the lithium battery, the surface of the aluminum shell of the lithium battery needs to be electrostatically sprayed to increase the service life of the aluminum shell of the lithium battery. However, when electrostatically spraying the aluminum shell of a lithium battery, it is easy to have a problem that the clamping angle causes a dead angle and the spraying cannot be in place.

[0003] The utility model patent with patent application number CN202222984265.2 discloses an aluminum shell surface treatment device for battery cell production, including a base plate and a carrier plate assembly, a clamping assembly and a spraying assembly arranged on the base plate. The structure can move in a horizontal direction relative to the vertical plate bracket to clamp the aluminum shell between the two vertical plate brackets and flip the aluminum shell 180°. It has the advantages of uniform spraying, no dead angles and a high degree of automation.

[0004] However, when this structure is actually used, when spraying the aluminum shell, the workpiece needs to be placed on a spray carrier, and the aluminum shell is sprayed using an electrostatic spray gun of a spray assembly. This may easily result in excess spray liquid dripping directly onto the spray carrier after the spray liquid is sprayed on the workpiece, which may not only easily cause environmental pollution, but also increase the waste rate of the spray liquid. In view of this, the utility model proposes a lithium battery aluminum shell surface treatment device. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a lithium battery aluminum shell surface treatment device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lithium battery aluminum shell surface treatment device, comprising a workbench, a bracket is arranged on the top of the workbench, a plurality of electric push rods are arranged on the top of the bracket, and a spray hood is installed together at the output ends of the plurality of electric push rods, the output ends of the electric push rods extend to the bottom of the bracket and are connected to the upper surface of the spray hood, the cross-section of the spray hood is larger than the cross-section of the mounting frame, a concave tube is arranged on the surface of the spray hood, and the front and rear sides of the concave tube are both connected with an L-shaped tube, a connecting tube is arranged at the top of the concave tube, a plurality of atomizing nozzles are connected on the side walls of the concave tube and the L-shaped tube, one end of the two L-shaped tubes are connected with the concave tube, the connecting tube is connected with the top of the concave tube, a plurality of atomizing nozzles are connected with the corresponding L-shaped tube and the concave tube, and one end of the atomizing nozzle is located inside the spray hood, and solenoid valves are correspondingly installed on the outside of the concave tube and the L-shaped tube.

[0007] It can be seen that in the above structure, after the spray hood covers the outside of the aluminum shell, it can avoid the diffusion phenomenon caused by the spraying process and reduce the pollution to the environment. Moreover, after the spray liquid is transported and sprayed through the concave tube and the L-shaped tube, the spray liquid can be evenly sprayed on multiple surfaces of the aluminum shell at the same time, thereby improving the spraying efficiency of the aluminum shell.

[0008] In order to reduce the waste caused by spraying liquid and avoid pollution, preferably, a collecting structure is provided on the surface of the workbench, and the collecting structure includes a mounting frame. A rectangular groove for mounting the mounting frame is provided on the surface of the workbench, and the mounting frame is installed inside the rectangular groove. A circulation port is provided inside the rectangular groove, and a filter is embedded and installed inside the mounting frame. A plurality of mounting holes are provided at the connection between the mounting frame and the rectangular groove, and bolts are threadedly installed inside the plurality of mounting holes. A pull groove is provided on the surface of the mounting frame, and a collecting chamber is provided at the bottom of the workbench directly below the circulation port.

[0009] In order to achieve a positioning effect when the spray hood is covered on the surface of the aluminum shell, preferably, two positioning grooves are provided at the front and rear edges of the workbench, and a positioning block adapted to the positioning groove structure is provided at the bottom of the spray hood.

[0010] In order to achieve the effect of clamping and flipping the aluminum shell, it is convenient to spray the contact surface between the aluminum shell and the filter screen. Preferably, both inner walls of the bracket are penetrated with movable grooves, and movable blocks are slidably arranged inside the movable grooves. A number of cylinders are arranged at the bottom of the workbench, and the output pipes of the cylinders extend to the inside of the movable grooves and are connected to the movable blocks inside the movable grooves. A threaded barrel is penetrated on the surface of the movable block, and the threaded barrel is rotatably connected to the movable block. A screw is installed on the internal thread of the threaded barrel, and an extrusion block is arranged at one end of the screw, and an adjustment block is arranged at the other end of the screw.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting up a collection structure, the aluminum shell of the lithium battery is placed on the filter. When the aluminum shell is sprayed, part of the spray liquid will be sprayed on the surface of the aluminum shell, and the other part of the spray liquid that falls will be filtered through the filter and directly enter the collection chamber for collection, thereby reducing the waste of the spray liquid. In addition, the operator can clean the filter inside the installation frame by tightening the bolts and pulling the installation frame out of the rectangular groove through the pull groove, thereby improving the subsequent filtering effect of the spray liquid;

[0013] 2. By using the electric push rod to drive the spray hood to extend downward and cover the surface of the aluminum shell that needs to be sprayed, the spray hood can spray the aluminum shell in a closed space to avoid the impact caused by diffusion in the air. The cooperation of the concave tube and the L-shaped tube can spray the electrostatic spray liquid on multiple sides of the lithium battery aluminum shell, achieving the effect of spraying multiple surfaces of the aluminum shell at the same time, thereby improving the spraying efficiency;

[0014] 3. The rotation of the screw can make the two extrusion blocks clamp the two sides of the aluminum shell. At the same time, the cylinder drives the movable block to slide upward inside the movable groove, which can lift the clamped aluminum shell to avoid interference when the aluminum shell is turned over. The operator can turn the aluminum shell by rotating the threaded barrel, so that the contact surface between the aluminum shell and the filter screen can be sprayed, thereby achieving a comprehensive spraying effect on the aluminum shell.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1-5 A lithium battery aluminum shell surface treatment device shown in the figure includes a workbench 1, a bracket 2 is arranged on the top of the workbench 1, a plurality of electric push rods 3 are arranged on the top of the bracket 2, and a spray hood 4 is installed together at the output ends of the plurality of electric push rods 3, the output ends of the electric push rods 3 extend to the bottom of the bracket 2, and are connected to the upper surface of the spray hood 4, the cross-section of the spray hood 4 is larger than the cross-section of the mounting frame 9, a concave tube 5 is arranged on the surface of the spray hood 4, and the front and rear sides of the concave tube 5 are both connected to an L-shaped tube 6, a connecting tube 7 is arranged at the top of the concave tube 5, a plurality of atomizing nozzles 8 are connected to the side walls of the concave tube 5 and the L-shaped tube 6, one end of the two L-shaped tubes 6 are connected to the concave tube 5, the connecting tube 7 is connected to the top of the concave tube 5, a plurality of atomizing nozzles 8 are connected to the corresponding L-shaped tube 6 and the concave tube 5, and one end of the atomizing nozzle 8 is inside the spray hood 4, and solenoid valves 18 are correspondingly installed on the outside of the concave tube 5 and the L-shaped tube 6.

[0023] Specifically, in this structure, when electrostatic spraying is performed on the surface of the aluminum shell of the lithium battery, the lithium battery needs to be placed on the workbench 1, and the electric push rod 3 is used to drive the spray hood 4 to extend downward and cover the surface of the aluminum shell to be sprayed. The spray hood 4 can spray the aluminum shell in a closed space to avoid the influence caused by diffusion in the air. At this time, one end of the connecting pipe 7 is connected to the electrostatic spraying equipment, so that the electrostatic spraying liquid enters the concave pipe 5 through the connecting pipe 7, and is divided on both sides at the concave pipe 5. At the same time, the concave tube 5 further diverts and transports the spray liquid through the two L-shaped tubes 6, and finally sprays the electrostatic spray liquid on multiple sides of the lithium battery aluminum shell through multiple atomizing nozzles 8, so that multiple surfaces of the aluminum shell are sprayed at the same time, thereby improving the spraying efficiency. The solenoid valve 18 outside the concave tube 5 and the L-shaped tube 6 can control the order of spraying multiple surfaces of the aluminum shell. If it is necessary to spray one side of the aluminum shell alone, it is only necessary to open the solenoid valve 18 of the corresponding surface pipeline and close the other solenoid valves 18.

[0024] In a specific embodiment, as shown in the attached Figure 1 , 4 As shown, a collecting structure is provided on the surface of the workbench 1, and the collecting structure includes a mounting frame 9. A rectangular groove 10 for mounting the mounting frame 9 is provided on the surface of the workbench 1, and the mounting frame 9 is installed inside the rectangular groove 10. A flow port 11 is provided inside the rectangular groove 10. A filter screen 12 is embedded and installed inside the mounting frame 9. A plurality of mounting holes are provided at the connection between the mounting frame 9 and the rectangular groove 10, and bolts 13 are threadedly installed inside the plurality of mounting holes. A pull groove 14 is provided on the surface of the mounting frame 9, and a collecting chamber 15 is provided at the bottom of the workbench 1, directly below the flow port 11.

[0025] Specifically, in this structure, when the lithium battery aluminum shell is placed on the surface of the filter 12 and sprayed, a part of the spray liquid on the surface of the aluminum shell will drip and cause pollution or waste after the spray liquid is sprayed on the surface of the aluminum shell. After the lithium battery aluminum shell is placed on the surface of the filter 12, a part of the spray liquid will be sprayed on the surface of the aluminum shell, and the other part of the spray liquid that falls will be filtered by the filter 12 and directly enter the interior of the collection chamber 15 for collection, thereby reducing the waste of the spray liquid;

[0026] The operator can tighten the bolt 13 and pull the installation frame 9 out of the rectangular groove 10 through the pull groove 14, so as to clean the filter screen 12 inside the installation frame 9 and improve the subsequent filtering effect of the spray liquid.

[0027] In a specific embodiment, as shown in the attached Figure 2 , 4 As shown, two positioning grooves 16 are provided at the front and rear edges of the workbench 1 , and a positioning block 17 matching the structure of the positioning grooves 16 is provided at the bottom of the spray hood 4 .

[0028] Specifically, in this structure, when the spray hood 4 is covered on the surface of the aluminum shell, the multiple positioning blocks 17 at the bottom of the aluminum shell can be placed in the positioning grooves 16 at the workbench 1, so that the spray hood 4 covers the aluminum shell to achieve a positioning effect.

[0029] In a specific embodiment, as shown in the attached Figure 1 , 5 As shown, both inner walls of the bracket 2 are penetrated with a movable groove 19, and a movable block 20 is slidably arranged inside the movable groove 19. A plurality of cylinders 21 are arranged at the bottom of the workbench 1. The output pipes of the cylinders 21 extend to the inside of the movable groove 19 and are connected to the movable block 20 inside the movable groove 19. A threaded barrel 22 is penetrated on the surface of the movable block 20, and the threaded barrel 22 is rotatably connected to the movable block 20. A screw 23 is installed on the internal thread of the threaded barrel 22, and an extrusion block 24 is arranged at one end of the screw 23, and an adjustment block 25 is arranged at the other end of the screw 23.

[0030] Specifically, the above structure is used to achieve the effect of clamping and flipping the aluminum shell when spraying, so that the contact surface between the aluminum shell and the filter screen 12 is sprayed. Specifically, after the other surfaces of the aluminum shell are electrostatically sprayed, the operator can hold the threaded barrel 22 and rotate the screw 23 through the adjustment block 25, so that the two extrusion blocks 24 clamp the two side surfaces of the aluminum shell. At the same time, the cylinder 21 drives the movable block 20 to slide upward inside the movable groove 19, which can lift the clamped aluminum shell to avoid interference when flipping the aluminum shell. The operator can flip the aluminum shell by rotating the threaded barrel 22, so that the contact surface between the aluminum shell and the filter screen 12 is sprayed, thereby achieving a comprehensive spraying effect of the aluminum shell.

[0031] Working principle of this utility model:

[0032] When the above structure is used in practice, when the aluminum shell of the lithium battery is subjected to surface treatment, it is necessary to perform an electrostatic spraying operation on the surface of the aluminum shell. Specifically, the aluminum shell is first placed on the surface of the filter 12, and the electric push rod 3 is used to drive the spraying hood 4 to extend downward and cover the surface of the aluminum shell that needs to be sprayed. The spraying hood 4 can spray the aluminum shell in a closed space to avoid the influence caused by diffusion in the air;

[0033] One end of the connecting tube 7 is connected to the electrostatic spraying equipment, so that the electrostatic spraying liquid enters the concave tube 5 through the connecting tube 7, and is diverted on both sides at the concave tube 5. At the same time, the concave tube 5 further diverts and transports the spraying liquid through two L-shaped tubes 6, and finally the electrostatic spraying liquid is sprayed on multiple sides of the lithium battery aluminum shell through multiple atomizing nozzles 8, so that multiple surfaces of the aluminum shell are sprayed at the same time, thereby improving the spraying efficiency. The electromagnetic valve 18 outside the concave tube 5 and the L-shaped tube 6 can control the order of spraying multiple surfaces of the aluminum shell. If it is necessary to spray one side of the aluminum shell alone, it is only necessary to open the electromagnetic valve 18 of the corresponding surface pipeline and close the other electromagnetic valves 18;

[0034] When the spraying of multiple surfaces of the aluminum shell is completed, the spray hood 4 rises, the operator holds the threaded barrel 22, and rotates the screw 23 through the adjustment block 25, so that the two extrusion blocks 24 clamp the two side surfaces of the aluminum shell. At the same time, the cylinder 21 drives the movable block 20 to slide upward inside the movable groove 19, which can lift the clamped aluminum shell to avoid interference when the aluminum shell is turned over. The operator can turn the aluminum shell over by rotating the threaded barrel 22, and continue to spray the contact surface between the aluminum shell and the filter screen 12;

[0035] During the spraying process of the aluminum shell, a part of the spray liquid will be sprayed on the surface of the aluminum shell, and the other part of the spray liquid that falls will be filtered through the filter 12 and directly enter the collection chamber 15 for collection, thereby reducing the waste of the spray liquid. The operator can tighten the bolt 13 and pull the installation frame 9 out of the rectangular groove 10 through the pull groove 14, and the filter 12 inside the installation frame 9 can be cleaned to improve the subsequent filtering effect of the spray liquid.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
